Google Desktop Search - Awesome Tool

Image
Hi Friends,

I found something very interesting something about google desktop search. I think, it is really useful to share with you people.

Google Desktop Search acts as your own personal Google Server and indexes the contents your system by file name, or in the case of select file formats, by the contents of the file. It runs on Windows XP and Windows 2000 (with Service Pack 3).

The free download indexes the full text of email created in Outlook or Outlook Express, Word documents, Excel spreadsheets, PowerPoint presentations, AOL Instant Messages, and caches the pages you view in Internet Explorer so you can revisit the page later "even if its live content has changed or you're offline."

The install is really simple and after you install it starts indexing. If you are working on your system then it will take a while to index. As soon as it realizes the machine is idle it starts churning away. After it indexes the data you are presented with a browser based interface much l…

Manipulating String intelligently

Image
Performance and Optimizations are the key features desired in Java Programming. So here are some examples, how to make improvement in your String manipulation..



String is the most encountered Objects in Java Programming. Till Tiger, we have 3 Classes to manipulate Strings. These are String, StringBuilder, StringBuffer.

String is immutable whereas StringBuffer and StringBuilder can change their values.

StringBuilder was introduced in J2SE5 or Tiger.The only difference between StringBuffer and StringBuilder is that StringBuilder is unsynchronized whereas StringBuffer is synchronized. So when the application needs to be run only in a single thread then it is better to use StringBuilder. StringBuilder is more efficient than StringBuffer.

Here are some examples given by Mr. Heinz Kabutz about how to perform String Manipulation intelligently.

We start with a basic concatenation based on +=:

public static String concat1(String s1, String s2, String s3,
String s4, St…

Calendar class - Better Way to Manipulate Dates.

Java’s Calendar class offers a set of methods for converting and manipulating temporal information. In addition to retrieving the current date and time, the Calendar class also provides an API for date arithmetic. Calendar’s built-in date/time arithmetic API is extremely useful. This tutorial examines the Calendar class API and presents examples of how you can use Calendar objects to add and subtract time spans to and from dates and times, as well as how to evaluate whether one date precedes or follows another.Adding time spansLet’s say you want to add a time span to a starting date and print the result. Consider the following example, which initializes a Calendar to 16 July 2007 and then adds two months and three days to it to obtain a new value:import java.text.SimpleDateFormat;import java.util.Calendar;import java.util.GregorianCalendar;public class CalenderDemo{ public static void main(String[] args) { CalenderDemo tdt = new CalenderDemo(); tdt.calculateDate(); } private void…

Reflection APIs - A way to inspect classes at runtime

Java Reflection is a technology that looks inside a Java object at runtime and sees basically everything about the object that you would know at compile time. Java Reflection is a technology that looks inside a Java object at runtime and sees what variables it contains, what methods it supports, what interfaces it implements, what classes it extends—basically everything about the object that you would know at compile time.The Reflection API is located in the java.lang.reflect package and is included in any J2SE installation. Primarily it is intended for very generic programs such as database browsers or visual code editors, but it can be used in any other applications. Reflection is for Basic techniquesThere are two basic techniques involved in Reflection: discovery and use by name. Here are descriptions of both:Discovery involves taking an object or class and discovering the members, superclasses, implemented interfaces, and then possibly using the discovered elements.Use b…

Java Singleton Pattern : Potential Problems and Solutions

The Java Singleton pattern belongs to the family of design patterns that governs the instantiation process. This design pattern suggests that at any time there can only be one instance of a Singleton (object) created by the JVM. You implement the pattern by creating a class with a method that creates a new instance of the class if one does not exist. If an instance of the class exists, it simply returns a reference to that object.How the Singleton pattern works:Here’s a typical example of Singleton:public class Singleton { private final static Singleton INSTANCE = new Singleton(); // Private constructor suppresses generation of // a (public) default constructor private Singleton() {} public static Singleton getInstance() { return INSTANCE; } }The classic Singleton does not use direct instantiation of a static variable with declaration — it instantiates a static instance variable in the constructor without checking to see if it already exists:public class C…

Struts Are the Really Very Beautiful..................

Three Days Before Struts started in Training program. I Heard that Struts are very difficult to understand. But After three days, I found how beautifully they are designed by the Craig R. McClanahan.

I also learned Here in current company that learning the concepts is very neccessary rather than just gulping the APIS. I really thank our instructor for this.

Hey I m not going to write about the struts, since web is just full of such kind of material. The spirit is to force urself to learn the basics of anything. Technology may change not the basic concepts.

Time to Take a Break.
